Haven't been here for some time...
I happened to be in Tiru this February and I saw all the posters for John de Ruiter.
It was the first time I've been there in high season for many years, and I was overwhelmed by what the place has become. What was once a tranquil settlement centered around Ramanashram is now a chaotic spiritual tourism hotspot. Apart from the ads for John de Ruiter there were also ads for Laughing Yoga and Chatsang (where you go just to chat about spiritual matters). Aura readings, astrology, Tantra -- it's all there. One yoga teacher even began putting up her posters on signposts on the hill -- I tore them down.
Very few of these people and the tourists who come to see them set foot inside Ramanashram, which thank goodness remains as free of commerce as ever. But it is sad to see what has become of one of the finest places in all of India.
Reading that blog reminded me of a BBC video I saw recently, in which one of the pseudo-gurus, Radha Ma, was feautured; I had never heard of her before but I saw her in this film and so went to the blog post about her to learn of how she died. Truly horrific self-immolation. Read about it here.
